"In the resting state the luminal domain of STIM1 binds Ca2+ ions within the endoplasmic reticulum and this binding prevents dimerization of STIM1 (Luik et al. 2008). Upon depletion of Ca2+ ions from the endoplasmic reticulum, STIM1 is no longer bound to Ca2+ and forms homodimers (Muik et al. 2008, Luik et al. 2008, Park et al. 2009)."^^ .
